WebThe absorption of light occurs when a ray of light strikes a surface. The energy from the light is transferred to the surface material. The transfer creates heat (usually small amounts). An absorbing surface prevents reflection or diffusion of light striking on the … WebLight absorption in PSII. When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. There, energy is transferred to P680, boosting an electron to a high …
WebJan 30, 2024 · Absorption Spectrum. The absorption spectrum is a graph that can be defined as a range of different wavelengths absorbed by a pigment. The cellular and molecular make-up of different species are the major factors that decide the range of absorption spectra, and therefore it differs in plants and different kinds of algae.
